Kingdom of Trinacria

The Kingdom of Trinacria was the name given to the Kingdom of Sicily from 1282 to 1412, during which it was ruled by the House of Barcelona. In 1282, King Pere III of Aragon intervened in Sicilian affairs after the Sicilian Vespers revolt against Angevin rule on the island, and the Aragonese would come to rule over the kingdom. The name "Trinacria" was first used to refer to Sicily after the Peace of Caltabellotta in 1302, which divided the old Kingdom of Sicily in two; King Frederick III of Sicily of the House of Barcelona would rule over Trinacria, while Charles II of Naples ruled the Kingdom of Naples on the Italian mainland. Sicily was ruled as an independent kingdom by relatives of the cadet branch of the house of Aragon until 1409, and it then became a part of the Crown of Aragon.
